Sean Kingston Crash -- Oh, The Hu-Manatee!

Sean Kingston ain't in the clear yet after crashing a high-speed jet ski into a Miami bridge -- TMZ has learned the singer could still face legal repercussions ... for disturbing the local manatees.

Law enforcement sources tell us ... the area where Kingston crashed last weekend is a manatee zone -- and according to Florida state law, boats and watercrafts are prohibited from producing a wake in manatee-populated areas.

Based on the jet ski damage ... Kingston probably produced a wake before his accident -- but law enforcement is still investigating to figure out exactly what happened prior to the crash.

If Kingston IS found in violation of the manatee law -- he faces a maximum fine of $32,500.
